California shipped approximately 18 million boxes of fresh peaches and nectarines in 1975. Seven test shipments were conducted in 1975 to determine if fruit could be shipped successfully in fiberboard boxes with net weights of 35 instead of 25 pounds. We also compared the relative advantages of Bliss-style and tray-style design corrugated fiberboard boxes. During 40 hours of transit, peaches averaged 54° F (12° C) in 25- and 35-pound fiberboard boxes. Nectarines averaged 48° (9° C) in the 25- and 35-pound fiberboard boxes during 96 hours of transit. However, these temperatures were higher than recommended for fruit shipments. All containers were in good condition on arrival, and no significant difference in fruit quality was detected between the fruit packed in the 25-pound fiberboard box or that packed in the 35-pound fiberboard box. About $1.5 million a year could be saved by using 35- instead of 25-pound corrugated fiberboard boxes for peaches or nectarines.
